摘　　要：在单光瞳图像处理系统中,扫描系统与非相干成像系统具有等价性,在此基础上设计了图像处理系统中的双光瞳处理系统,并推导了该系统在聚焦和离焦时的光学传递函数,提出了离焦时该系统在光学扫描全息术中的应用.The equivalence between the scanning system and the non-coherentimage system in the one-pupil image processing system was reviewed. On thisbasis, the optical transfer function both in the focused system and in the defo-cused system were derived. Finally, the optical transfer function synthesis in thedefocused case was carried out and its application to the optical scanning hologra-phy were proposed.
